TRESTLE-IBRACKET.

Specification of Letters Patent.

Patented Nov. 3, 1914.

Application filed February 13, 1914. Serial No. 818,564.

To all whom it may concern:

Be it known that I, JAMES M. CANFIELD, a citizen of the United States, residing at Dallas City, in the county of Hancock and State of Illinois, have invented new and useful Improvements in Trestle-Brackets, of which the following is a specification.

The present invention aims to facilitate the construction of trestles for carpenters and other mechanics requiring a temporary support for work, or scaffolding to reach overhead places.

The ordinary trestle commonly used for carpenters is constructed of studding and comprises a head, or body, and legs, the latter being usually nailed at their upper ends to opposite sides of such head or body. The end portions of the legs adjacent the sides of such head or body of the trestle are usually beveled or cut away at an angle to enable such ends to obtain a snug fit against the sides of the head. Such trestles require considerable skill and time in their construction.

The present invention provides a metal bracket of such shape as to enable the studding to be cut into desired lengths and quickly placed together and secured, thereby resulting in the formation of a trestle in which the legs have substantially the same set and whereby the metal parts and fastenings are so located as notto injure the teeth of saws or the edge of tools.

The invention provides a bracket which is constructed of a sheet metal blank bent into peculiar form, the overlapping parts being secured by the same fastenings employed for attaching the legs thereto.

The inventionalso further consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.

In the drawing hereto attached, Figure 1 is a detail view in perspective of the end portion of a trestle embodying the invention. Fig. 2 is a view of the bracket inverted, the dotted lines indicating the posi tion of the head and legs of the trestle. Fig. dis a perspective View of the bracket inverted and as seen directly from the front. Fi 4 is a longitudinal section.

orresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

The bracket comprises a top 1, end 2 and sides 3. The end 2 is formed at its edges with wings 4 which come against the inner sides of the parts 3. The several parts of the bracket constitute elements of a single blank of sheet metal of proper gage so as to provide a substantial and durable article. The top 1 is formed with openings 5 to receive suitable fastenings bv means of which the head or body 6 of the trestle is secured to the bracket. The sides 3 and wings 4 are formed with openings in coincidentrelation to receive fastenings by means of which the legs 7 are fastened to the bracket. It is observed that the sides 3 and wings 4 are connected to one another and to the legs 7 by the same fastening means 8 which may be of any nature such as bolts, screws or the like. The legs 7 are preferably arranged exterior to the side pieces 3 so as not to project beyond the sides of the head or body 6 and moreover such legs come beneath the head or body 6 and form a substantial support therefor.

It is to be understood that a pair of brackets are required for each trestle and such brackets may be nested so as to occupy a comparatively small amount of space. lVhen it is required to construct a trestle the studding or other lumber is simply cut into proper lengths. the brackets being secured to the underside of the head or body 6 by suitable fastening means after which the legs 7 are placed in position and secured by fastenings 8. The brackets enable a trestle to be quickly and properly constructed, the legs 7 having a like set so that the trestle may be used with accuracy for supporting the work or as an element in the formation of a scaffold.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the invention as claimed.

Having thus described the invention what is claimed as new, is

1. A trestle bracket embodying a top, oppositely inclined sides, an end and wings at opposite edges of the end, the top, sides, and wings having openings to receive fastenings and the wings being secured to the sides by means of the same fastenings employed for attaching-the legs of the trestle to the bracket.

2. A trestle bracket formed of a single blank, and comprising a top, end and oppositely inclined sides, and wings at the edges of the end and arranged to come against the inner faces of the said sides, the top, sides and wings having openings to receive fastenings, the openings in the wings being in JAMES M. OANFIELD.
